Application filed October 12, 1920. Serial R0. 416,484. TOJZZZ whom it may concern: I

Be it known that I, DONALD W. MGLEAN, a citizen of the Dominion of Canada, residing at Glencoe, in the county of M ddlesex and Province of Ontario, vented certain new and ments in Generators, is a specification.

Like symbols are used to indicate corresponding parts throughout the drawings.

Referring to the drawings, A represents the improved generator comprising a cylinder or cylinders 1, arranged in alinement, and between these cylinders a prime mover and valve gear 2 is located, but this prime mover and valve gear does not form part of Canada, have inthe present invention and consequently is not described.

A piston rod 3 passes through the casing of the prime mover 2 and is formed with reduced ends which are threaded at 4 and these threaded ends are screwed into a water piston 5. y

This water piston fits within a gas piston 6 and is retained therein'by an adjustable nut 7 and a water sp e 8'is left between the inner end of the gas, piston 6 and the water piston 5.

In the water piston 5 a recess is formed in the inner end as indicated at 9, and a valve seat 10 is screwed into the end of this recess and a valve 11 engages with the valve seat and has its stem extending through the same.

A spring 12 encircles the stem of the valve and engages with the inner face of the valve seat 10 and with a pin which extends through the valve stem. The recess 9 forms a chamber which is in communication with the bore hole 13 ton rod 3 and the is designed to be which is attached A collar 16 is extending through the pisouter end of this bore hole connected to a rubber tube to a water tank.

threaded around the inner end of the water piston 5 and engages with a packing member 17, so that the water piston makes a water tight joint with the gas piston 6.

The gas piston 6 is fitted with rings 18 so that it makes a gas tight engagement with the cylinder 1, and on the inner end of the gas piston 6 a valve seat 19 is provided with which the valve 20 engages.

A recess 21 is formed in the; gas piston 6 to accommodate a nut 22 which is screwed on the stem of the valve 20, and this nut is provided with a series of radial grooves 28 to allow water to pass by the nut and through the valve seat into the cylinder.

The spring 24 which encircles the nut 22 controls the closing of the valve 20.

The cylinder 1 is provided with a gas chamber 25 around its outer wall, and this gas chamber communicates with the cylinder through ports 26, and the gas chamber is connected by a pipe 27 with the carbureter which is attached to the gasolene tank.

On the end of each cylinder 1 an exhaust chamber 30 is provided and formed with a valve seat 31 with which the valve 32 engages, and this valve is provided with an outer piston end 33 having a recess therein to accommodate a spring 34. A cover 35 fits over the piston 33 and is secured to the exhaust chamber 30 by bolts or other'fastening means.

Through the end of the cover an adjustable screw 36 extends and en ages with a plate 37 which bears against t e spring 34, and the cover is provided with a vent 38.

The exhaust chamber 30 is connected to a pipe which communlcates with the hollow members 41 and delivers a mixture of superheated steam and products of combustion to the said hollow members. A detail of the hollow members is shown in Figs. 6 and 7.

The hollow members 41 are closed at one end by a cap 42 and are provided with a number of nozzles 43, and the hollow members are sectional, the outer section being connected to the inner section by a stufiin box mechanism 44, and a spring is coile round the outer section and has one end attached to the said outer section and the other end attached to the stufling box. This spring is indicated at 45.

On the inner section of the hollow members which do not rotate, valves 46 are provided and these valves are controlled by links 47 and a T-shaped lever 48 which is pivoted to the supply pipe 49 of the hollow members.

The T-shaped lever 48 has a weight 50 on the end of its vertical member.

The movable outer section of the hollow member 41 has a wire 51 coiled therearound, and when the wire is pulled, the outer sec-. tion of the hollow member will rotate so that the nozzle 43 will be disposed in the proper direction.

When the generator is being used, the piston rod 3 is reciprocated, and water flows from the tank 15 through the tube 14 to the bore hole 13, and enters the recess 9, and on the inward stroke of the gas and water pistons 6 and 5, a vacuum is created in the space 8 and the valve 11 is unseated and water fills the said space.

When the piston 6 reaches the inner end of its stroke, the ports 26 are uncovered and gasolene flows from the tank 29 to the carbureter 28 and through the pipe 27 to the chamber 25, then through the ports 26 into the cylinder.

On the return stroke of the pistons 6 and 5, the water is compressed in the space 8 and the gasolene which has been vaporized is compressed in the cylinder up to a pressure at which it ignites, and the pressure of the water unseats the valve 20 and sprays the water into the cylinder where it absorbs the heat of the burning gasolene, vaporizes the water and forms superheated steam which will have the products of combustion of the gasolene suspended therein.

When the piston '6 is reaching the end of its stroke, it unseats the valve 32, and the superheated steam and products of combustion pass into the exhaust chamber 30, and through the pipe 40 to the non-rotatable portion of the members 41, where the superheated steam passes through the valves 46 to the movable portions of the members and is discharged through the nozzles 43.

On the inner stroke of the pistons 6 and 5, the valve 32 is re-seated by'the spring 34 and the operation of receiving water into the water space 8 is repeated, while gasolene in a vaporized form will be delivered to the cylinder when the piston 6 has reached the inner end of its stroke.

The vaporizing of thewater and the formation of steam takes place on the outer stroke of the pistons as has been described above.

Should an aeroplane on which this device is installed be flying forward in a strai ht course, and tip sidewise, then the T-va ve 48 will be held in a true vertical position by gravity, and the valve 46 on the highest side of the member will be closed shutting oif the superheated steam from the member and allowing the steam to be delivered only to the lower portion of the member, from which it will be discharged through the nozzle 43 and will act as a stabilizer and return the aeroplane to a normal horizontal position.

When the aeroplane returns to its horizontal position, the T-shaped lever 48 will automatically open both valves 46 so that the steam is now delivered to both sides of the member.

By means of the wire 51, the nozzles can be turned in any desired direction. If desirous of rising, the nozzle will be turned downwardly so that the gases discharged therefrom will raise the aeroplane. When raised they may be tilted rearwardly and slightly downwardly and in this position will give a forward driving power. In turning, the nozzles on the imier side can be directed slightly more in a downward direction than those on the outer side and in this way the aeroplane will be held in a horizontal position 'while the outer nozzles being directed rearwardly will bring the outer side around to turn the curve as desired.
